A new mussel-inspired polydopamine phototransistor with high photosensitivity: signal amplification and light-controlled switching properties†
Abstract
A polydopamine (PDA) thin film with a dense and conformal surface was prepared under optimized deposition conditions using O2 gas as an oxygen source. The PDA-based organic phototransistors exhibited high photosensitivity and photo-controlled switching properties under light illumination.
